Laravel Array:Key 验证

Question

我的 Laravel 后端收到一个 JSON 转换的 Javascript 数组并将其解码为以下 php 数组：

dd($cart) 已编辑密钥已更改

array:4 [▼
  "personcount" => 2
  "person1" => array:2 [▼
     "Customer" => array:2 [▶]
      "Items" => array:5 [▼
        "key1" => 0
        "key2" => 0
        "key3" => 0
        "key4" => 0
        "key5" => 1
      ]
       
  ]
  "person2" => array:2 [▼
     "Customer" => array:2 [▶]
     "Items" => array:5 [▶]
  ]
]

我创建了一个过滤器中间件，它应该验证给定的数组并在失败的情况下重定向回来。

Filter.php 已编辑添加了新的（无效的）验证规则方法

$cart = json_decode($request->input('cart'), true);

$validation_rules = [];

$TotalItemCount = 0;

for ($i = 1; $i <= $person_count; $i++) {

    foreach ($cart[$i]["Items"] as $Item => $ItemCount) {
        $TotalItemCount += $ItemCount;
    }

    $validation_rules += [
        "person$i.Customer.FirstName" => "required|string|min:2|max:255",
        "person$i.Customer.LastName" => "required|string|min:2|max:255",
        "person$i.Items.*" => "required|numeric",
        "person$i.Items" => ['required', 'array',
                    Rule::in(["Key1", "Items"]),
                ],
    ];
}
$validated_input = Validator::make($cart, $validation_rules);

验证器似乎忽略了 $i.Items 验证规则。我什至将 size:5 更改为 size:6，这不得不 100% 触发错误，因为给定的项目数组总是只包含 5 个元素。

此外，我尝试验证数组键：

"$i.Items" => "required|array:key1,key2,key3"

它也根本没有开火。我想要所有的钥匙。 firstName/Lastname 规则适用。

我很乐意提出建议。

Answer 1

而不是

 "required|array:key1,key2,key3"

你会做类似的事情

'required|in:' . $this->array() . ''

Answer 2

经过大量研究和努力，我找到了解决方案：

对于在 Laravel 8+ 中拼命搜索高级数组验证示例的每个人：

Step: ALWAYS use an array, not an object. For that purpose:

public function fCreateArrayFromObject($Object) {
            $toArray = function ($x) use (&$toArray) {
                return is_scalar($x)
                    ? $x
                    : array_map($toArray, (array)$x);
            };
   
return $toArray($Object);
}

Step: I will use my example to show you how its easily done:

My array ($cart):

array:3 [▼
  "user1" => array:2 [▼
    "Items" => array:5 [▼
      "blue" => 0
      "grey" => 1
      "brown" => 1
      "look" => 0
      "black" => 0
    ]
    "User" => array:2 [▼
      "LastName" => "alice"
      "FirstName" => "Bobby"
    ]
  ]
  "user2" => ......
]

My rules:

$person_count = 2; // Up to 5

$validation_rules = [];
        
        for ($i = 1; $i <= $person_count; $i++) {

            $validation_rules += [
                "user$i" => "array:Items,Customer|size:2|distinct",
                "user$i.user.FirstName" => "required|string|min:2|max:255",
                "user$i.user.LastName" => "required|string|min:2|max:255",
                "user$i.Items.*" => "required|numeric|min:0",
                "user$i.Items" => "required|array:blue,grey,brown,look,black|size:5|distinct",
          
            ];
        }

Action:

$validated_input = Validator::make((array)$cart, $validation_rules);

我不太确定，为什么 make 方法不能将没有 (array) 的 $cart 数组解释为数组，但它可以工作。目标：

验证整个购物车：必须将每个人包含为一个恰好包含 2 个元素的数组（最多五个人数组）works
验证每个人本身：必须包含用户和项目数组 works
验证用户数组：必须包含 2 到 255 个字符的名字和姓氏，每个字符都是字符串 works
验证 Items 数组：必须完全是 size:5，必须包含所有给定的键 works
验证 Items 数组的键值：它们必须是数字并且至少为 0 works

显然一切都必须存在：“必需”
